DUIVIPING-CAR.

EPECIFIOATION forming part of Letters Patent No. 706,254, dated August5, 1902. Application filed January 27, 1902. Serial No. 91, (N0 model-lTo all 111700711, 211; may concern.-

Be it known that I, FRANCIS PETELER, of Minneapolis, Hennepin county,Minnesota, have invented certain new and useful Improvements inDumping-Oars, of which the following is a specification.

Theinvention relates to portable dumpingcars, and is designed as animprovement over the car shown and described in Letters Patent of theUnited States issued to me January 1, 1895, No. 531,746.

The primary object of the present invention is to provide a car that isadapted to dump on each side and is capable of receiving and dischargingwith ease and rapidity the largest masses of earth and rock that asteam-shovel can handle.

A further object is to provide a gravel and rock dump-car that can beeasily and quickly converted into a flatcar.

Other objects of the invention will appear from the following detaileddescription.

The invention consists generally in a dumpcar having its doors mountedupon movable standards or posts to permit the car to be dumped on bothsides.

Further, the invention consists in providing doors that are readilyremovable from the car-body and as easily replaced thereon, whereby thecar is adapted for use either as a dump or a flat car.

Further, theinvention consists in providing pivoted bolsters WhGI'GOHthe car-body rests when in ahorizontal position and which can be readilyswung down to permit the car to dump on either side.

Further, the invention consists in various constructions andcombinations, all as hereinafter described, and particularly pointed outin the claims.

In the accompanying drawings,forming part of this specification, Figurel is a side elevation of a dumping-car embodying my invention. Fig. 2 isan end view showing the carbody in its horizontal position. Fig. 3 is asimilar view with the car-body tilted, showing the relative position ofthe doors and the body. Fig. 4 is a transverse vertical sectionshowingthe mechanism for preventingthe carbody from tilting prematurely,the tilted position of the bodybeingindicated by dotted lines.

Fig. 5 isa detail of a portion of a bolster provided upon each side ofthe car. Fig. 6 is a detail perspective of the device for supporting thecar-door on the swinging standards. Fig. 7 is a detail of the pivots orgudgeons of the door. Fig. 8 is a perspective of the lever mechanism,whereby the swinging bolsters are controlled. Fig. 9 is a detail of themechanism for locking the bolster-operating mechanism to prevent itspremature moveinent.

In the drawings, 2 represents the angle side bars of the truck-frame; 3,the cross-bars supporting the longitudinal bed-timbers 4, upon which thelower members 5 of the rockercastings are secured, the upper members 6thereof being arranged upon the under side of the car-body. These partshave been in use in cars of my manufacture for a number of years, and Imake no claim to the invention therein in this application.

'7 represents the angle-bar sills, and 8 the channel cross-bars of thecar-body, bolted securely together and carrying the planking or floor 9.

At the corners of the car I provide posts 10, connected by the planking11,which forms the ends of the car-body.

12 represents the doors of the car, provided with the gudgeons 13, thatare mounted in castings 14 on the upper ends of pins, 15. These pins fitloosely within sockets in the castings 16, that are secured to standards17, whose lower ends are connected by hinges 18 with the bed-timbers 4,near the lower edges thereof. When the doors are in their nor malposition, the castings 14 will rest upon the upper ends of the standard17, and I prefor to provide recesses 19 in the posts 10 to receive saidcastings and the ends of said standards, which are preferably cut awayto present broad bearing-surfaces to said posts, so that the doors willbe securely supported and rigidly held at the top against outwardpressure of the contents of the car. Outward swinging of the doors whenthe car-body is horizontal is prevented by the stops .12. When thecar-body is returned to its horizontal position after dumping, thestandards supporting one of the doors and the cornerposts on that sidewill come together with considerable force, and, if preferred, theengaging surfaces may be faced with plates of metal to prevent unduewear thereof.

Upon the draw-bars 20, at each end of the car, I provide cross-timbers21, secured by any suitable means and braced near their ends by rods 22,and provided with angle-bar stops 23, which engage the standards 17 andlimit the outward swinging movement of the same. The timbers 21 arearranged a sufficient distance from the ends of the car to allow thestandards to be inserted and swing freely between them, and thesetimbers and the planking of the car form guides for said standards andprevent lateral twisting or swaying of the same. \Vhen the car is in itsnormal horizontal position, as shown in Fig. 2, the standards will be atthe limit of their outward swinging movement, and upon tilting the carin either direction the standards on that side of the cartoward whichthe body is tilted will remain stationary, supporting the swinging door,which will be suspended above the tilted floor of the body a suificientdistance to allow masses of earth or rock to slide out beneath, the doorswinging freely to permit any unusually large mass to pass out whichcould not pass out if the door was rigid. If it is desired to dump thecar on the opposite side,the standards on that side of the car oppositethe direction of dumping will be swung up to an upright position, asshown in Fig. 3, and as the standards are swung up the door will beraised vertically, the pins 15 sliding easily in their sockets until thecar-body has been tilted to the desired angle. The standard and doorwill remain in their raised position until the contents of the car hasbeen dumped and will return automatically to their normal position whenthe car is again horizontal.

In my former patent above referred to only one door was shown pivotedupon fixed standards on one side of the car, and with this manner ofsupporting the door it was not possible to tilt the car in the oppositedirection, even if a door had been provided on that side. Thisconstruction limited the use of the car and rendered it objectionable inplaces where dumping on both sides was necessary or desirable. Mypresent construction, however, obviates all this difficulty, as the carcan be tilted and dumped on both sides with equal facility.Theswinging-doorsupported standards will automatically adjust themselvesto the tilted or horizontal positions of the carbody, and the door willremain stationary or will be raised vertically on its supports,according to the direction that the car is tilted. In tilting the car inone direction and raising the door on the opposite side, as shown inFig. 3, it is necessary to provide means for preventing. thedoor-gudgeons from slipping down the inclined edges of the car ends, andI therefore provide straps 24, secured within recesses in said ends nearthe posts 10 and provided with stops 25, which engage said gudgeons andprevent the door from slipping out of its proper position when thecastings 14 are lifted away from the ends of the standards.

As heretofore stated, the pins 15 are freely slidable within thecastings 16 and may be readily slipped out of the same to permit thedisengagement of the doors from the car. The car can thus be convertedfrom a dumping to a flat car without the removal of bolts or the use oftools of any kind, it being merely necessary to raise the ends of eachdoor sufficiently to lift the pins out of their sockets. Thisconstruction is also of great convenience in shipping the cars, as thedoors can be loaded and handled separately from the carbody and put inplace when it is desired to use the car for handling and dumping gravel.

In my former patent I provide a fixed bolster on the side of the caropposite from the direction in which it dumps to support the body whenin a horizontal position, and I also provide chains to prevent prematuretilting of the car. In the present construction I dispense entirely withthe chains and employ a similar bolster which is pivoted to permit thecar to be tilted on both sides.

26 represents bolster-bars upon each side of the car, mounted uponstandards 27, that are pivoted at their lower ends upon lugs 28,provided on bosses 29 on the plates 30, secured to the side angle-bars2. The ends of the standards 27 rest upon the bosses 29, as shownclearly in Fig. 5, so that if the car is overbalanced on one side theweight will be borne by the bosses and the side bars and not upon thepivot-pins, which might be cut or sheared off by the strain. I haveshown two of the standards 27; but a greater number may be employed in acar having a larger capacity.

Upon the bolster-bars 26 I provide castings 31,wherein idle wheels orrolls 32 are mounted a'suflicient distance from the ear-bottom to rollfreely thereon and permit the bolsters to be swung in toward the centerof the car in dumping or returned to their normal position to supportthe body against tilting.

Various means may be provided for operating the swinging bolster-bars;but I prefer to provide a mechanism substantially as shown and describedherein. This mechanism consists in a pin 33, mounted in a casting 31L oneach bolster-bar and adapted to turn freely therein and pivotallyconnected with a rod 35, that extends under the carbody and is pivotedto the short arm 36 of a lever that is pivoted to the under side of thecar-body, and has a long arm 37 extending at an angle to the short armto the opposite side of the car-body and provided with a handle 38, thatis in position to be grasped by the operator to swing the bolster on theopposite side of the car in toward the center and allow the car to betilted toward that side. The car is provided on each side withcorresponding operating-levers for swinging the bolsterbar on theopposite side. To limit the movement of the levers 37, I provide stops39 on the side bars 7 and also arrange straps l0 thereon, between whichand said bars I pivot eccentrics 41, between which and the stops 39 thelevers are securely locked. The eccentrics are provided with lugs 42, tobe grasped by the finger for swinging the eccentrics and releasing saidlevers. Upon the bed-timbers t I provide cross-bars 43, which limit theinward swinging movement of the bolsters, and upon the side bars 2 Iarrange the bumper-castings 4:4, with which the carbody engages whentilted. In a car of the capacity shown I provide three sets of therocker-castings one in the middle and one at each end of thecar-body-and when a casting is provided in the middle I prefer toprovide offsets in the pivoted rods 35 to clear the upper member of thecasting. In cars of a larger size, however, where four sets of castingsare provided-two at each endthe offsets in these rods will not benecessary. The pins to which the rod 35 are connected turn freely intheir sockets, as described, and being pivotally connected with the rodswill allow the bolster-bars to swing freely without any binding orcramping of the operating mechanism, and as these pins are readilydetachable from the castings 34 the car-body can be quickly and easilyremoved from the trucks whenever desired.

This car is adapted for use wherever it is desired to dump on bothsides, as in railroadwork, and the doors being suspended several feetabove the bottom of the car when tilted will allow the contents to berapidly discharged without being in any way obstructed by the lowerportion of the door. Should any very large masses of earth or rock beloaded on the car, the lower edges of either one of the doors when thecar is tilted to unload will upon being engaged by the earth or rockswing outward and allow the load to slide out. The doors and theirsupporting-standards will adjust themselves automatically to thehorizontal and tilted positions of the carbody and need not be handledby the operator in any way in tilting the car or swinging it back to itsnormal horizontal position. The standards are protected by the ends ofthe car and by the horizontal cross-timbers and serve as firmsubstantial supports for the doors when the car is used for dumping andwhenever desired, as in shipping, or when the car is used as a flat-carmay be easily and quickly detached from the truck-frame.

To convert the dumping-car into a flat-car, I may simply remove thedoors from the standards, leaving the latter secured to the frame. henused as a fiat-car, the swinging bolsters may be locked in position andthe car prevented from tilting in either direction, or it may be tiltedany time by the operation of the lever mechanism.

In various ways the details of the mechanism herein described may bemodified, and I therefore do not wish to be confined to the particularconstruction set forth.
